I'm a huge fan of the print-on-demand 2E versions that have been coming out, but this book is a huge disappointment. The original (and the PDF) are printed on shaded paper with a mildly dark background. The POD version, however, is printed on white paper. Tons and tons of text in the book is unreadable because the original font is a light-greenish-yellow, and printing isn't crisp enough to make it bearable.
Of course, the book itself was and is amazing; one of the finest Planescape offerings. Unfortunately, the print-on-demand version is practically useless to me.
